In the drawings, Figure 1 is a side view of my improved cotton-press, and Fig. 2 shows a vertical section of part of the pressthrough line at of Fig. 1. Fig. 3 is a plan view of the gearing. Fig. 4 shows the key that secures the follower to the screw.

A A are the sills of the press, to which the standards Bfour in number-are firmly secured and braced by cross-braces c c. The bed-plate D rests on the sills A A, and its ends are secured-between the standards B. The baling-box E is situated upon the bedplate, and is secured against lateral or vertical displacement by means of cross-braces F. This box is provided with ordinary detachable doors G G, the end doors G having links 9 secured to the ends of cleats b, and side doors are provided with cam-headed levers H. As the doors are placed in position preparatory to compressing, the links 9 are swung over the heads of levers H, which, in turn, are pivoted, and serve to firmly secure the doors to the baling-box. Through a heavy cross-beam, I, resting on cross-braces c 0, passes a screw, J, to the lower end of which the follower is secured in a self adjustable manner. To the under side of cross-beam I a large supporting and steadying nut, K, is secured, while a bearing-plate, L, is placed on top of the beam, and in line with nut K. The hub or central bearing of bevel-gear wheel M rests upon the bearing-plate L, while the latter, when worn, may easily be removed and replaced by a new plate. Within the interior of the hub gearwheel M is secured a feather or spline, d, which engages in a groove, 0, formed in the screw J, and serves to lock the gear-wheel to the screw, and also allows of free vertical movement of the screw through the wheel. A horizontal shaft, N, has its bearing in a box formed in one of the cross-braces, c, and to said shaft is secured a small bevel-gear wheel, 0, the cogs of which mesh with those of the large wheel M. Immediately beneath the gear-wheel 0 an anti-friction wheel, P, is journaled in suitable bearings secured to the cross-beam I. This anti-friction wheel P supports the large bevel-wheel M at a point where the power is applied, and therefore, should the bearing-plate L become worn, the cogs of the wheels are not liable to shear orbe otherwise injured, as the anti-friction wheel P serves to preserve a perfect mesh between the cogs of the wheels M and 0. Again, should the anti-friction wheel be dispensed with, the bearing-plate L, when worn, will .cause the large wheel M to run untruly on the screw J, and, as the power is applied on one side of the large gear-wheel M, the threads of screw J would soon be cut away, and the screw thereby rendered useless.

The follower Q is recessed at f to form a step for the round end of the screw J.

A collar, h, engages in a groove, i, formed in the lower portion of the screw J, and said collar is secured against the top of follower Q by means of a plate, R.

The follower, when secured to the screw as described, has sufficient play to render it selfadjustable on the cotton to be compressed.

The follower and lower platen are provided with the usual transverse grooves for the reception of the bands used in baling cotton.

Fig. 3 shows a system of gearing, whereby the screw may be raised or lowered by simply manipulating a belt-shifter. As this is a matter of common information, a detail description of the same is not deemed necessary.

The belts may be supplemented by coggearing, and the same object thereby accomplished.

What I claim, and desire to secure by Letters Patent, is

1. The bevel-gear wheel M, locked to the screw J by means of feather and groove d e, in combination with the horizontal shaft N, bevel-gear wheel 0, and anti-friction wheel P, the latter located immediately beneath the gear-wheel 0, substantially as and for the pur- In testimony that I claim the foregoing I pose specified. have hereunto set my hand. a
